Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is a method for transporting substrates such as ceramics used for circuits in a vertical state.
The present invention relates to a substrate transport device.

[Conventional technology]

In general, a substrate made of ceramic or the like is formed into a rectangular shape having a predetermined length, and after being subjected to blast cleaning, it is transported to a drying chamber where it is washed and dried.

However, in the past, the substrate that had been blast cleaned at an angle was moved horizontally on rollers and then transported in that state into a drying chamber, which resulted in uneven cleaning and drying on the top and bottom surfaces of the substrate. However, the drawback was that the quality and performance of the product were adversely affected and high reliability could not be obtained.

[Problem that the invention attempts to solve]

The present invention was proposed in view of the above-mentioned conventional drawbacks, and is an inexpensive substrate that can clean and dry both sides of the substrate evenly and evenly, and that can transport the substrate continuously and stably. The purpose is to provide a conveyance device.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention aims to move the lower edge of a vertically erected substrate having a predetermined length into a concave groove provided on the upper surface of a lower edge support belt that is stretched horizontally and driven. This point was supported by Another feature is that both sides of the upper end of the board are sandwiched between both upper end support belts, which are provided in two parallel rows and driven in the same direction at the same speed as the lower end support belt. It is designed so that it can be transported while standing vertically.

[Effect]

Since the substrate transfer device of the present invention is configured as described above, the lower edge of the vertically erected substrate is supported within the groove provided on the upper surface of the lower end support belt, and both sides of the upper end are supported. is conveyed while being held between both upper end support belts. Therefore, if this substrate transfer device is used to transfer the substrate after blast cleaning to the drying chamber, both sides of the substrate will be evenly and uniformly cleaned and dried while the substrate is being transferred vertically. It turns out.

Furthermore, since the lower edge and both sides of the upper edge of the substrate are supported and clamped by the belt, even if the width, length, etc. of the substrate changes, it is continuously and stably conveyed.

〔Example〕

Next, the present invention will be specifically described based on embodiments shown in the drawings.

Figure 1 shows the arrow A-- in Figures 2 and 3.
FIG. 2 is a plan view of a substrate transfer device showing one embodiment of the present invention, and FIG. 3 is a side view thereof.

In the figure, reference numeral 1 denotes a vertically erected board having a predetermined length, the lower edge of which is supported within a concave groove 3 provided at the center of the upper surface of a lower end support belt 2 stretched horizontally. There is.

The lower end support belt 2 is stretched between the drive pulley 4 and the driven pulley 5, and is supported by guide rollers 6 in the middle so as not to sag. Note that the drive pulley 4 is fixed to the tip of a rotating shaft 8 supported by a bearing 7. 9 is a sprocket that connects the rear end of the rotating shaft 8 and the power unit 1.
0, and a chain 12 is wound around both sprockets 9,9.

Next, reference numeral 13 denotes an upper end support belt that clamps both sides of the upper end of the substrate 1. Both upper end support belts 13, 13
are provided in two rows in parallel, and the presser roller 1
It is strung between 4 and 14. Note that the upper end support belt 13 is driven in the same direction at the same speed as the lower end support belt 2, but an auxiliary presser roller 15 is provided on the inside midway along the way to clamp both facing belt surfaces, and an auxiliary press roller 15 is provided on the outside. is provided with an adjustment roller 16 for adjusting belt tension.

Further, the presser rollers 14 are each fixed to the lower end of a rotating shaft 18 that is vertically supported by a bearing 17, and a bevel gear 19 is fixed to the upper end of the rotating shaft 18.

20 is a bearing 22 installed on the frame 21
A rotating shaft supported horizontally by a rotating shaft, and in the middle thereof, bevel gears 23, 23 that mesh with bevel gears 19, 19 fixed to the upper end of the vertical rotating shaft 18, respectively.
is fixed. Next, a sprocket 24 is mounted on the right end of the rotating shaft 20, and bearings 7, 7 of the rotating shaft 8 are mounted on the right end of the rotating shaft 20.
A sprocket 25 is fixed between each.
A chain 26 is wound around both sprockets 24 and 25.

Note that 27 is the wall surface of the drying chamber, and the inside temperature is controlled to be constant.

According to the substrate transfer device of the present invention having the above configuration, when the power unit 10 is turned on, the rotating shaft 8 is rotated by the chain 12, and the lower end support belt stretched between the driving pulley 4 and the driven pulley 5 2 will be driven. Further, when the rotating shaft 8 rotates, the rotating shaft 20 is rotated by the chain 26, and the rotating shaft 18 is rotated via the bevel gears 23, 19, and both upper end supports stretched between the presser rollers 14, 14 are rotated. The belts 13, 13 are driven at the same speed and in the same direction as the lower end support belt 2.

Therefore, when the substrate 1 that has been blast-cleaned in the previous process is fed in from the right side in the direction of the arrow, the lower edge of the substrate 1 will fall into the groove formed on the upper surface of the lower-end support belt 2, which is stretched horizontally and driven. Supported within the strip 3, both sides of the upper end of the substrate 1 are sandwiched between both upper end support belts 13, 13 and conveyed sequentially to the left side, and both sides of the substrate 1 are evenly and uniformly cleaned during conveyance within the drying chamber. It will be dried. Note that the intervals between the guide rollers 6 and the auxiliary pressing rollers 15 may be designed in consideration of the length of the substrate 1 to be transported, the length of the drying chamber, and the like.

[Effect of idea]

As specifically explained above, according to the substrate transfer device of the present invention, the lower edge of the substrate is supported within the groove strip provided on the upper surface of the lower edge support belt, and both upper side surfaces of the substrate are supported at both upper edges. Since the substrate is held between support belts, it is possible to convey the substrate continuously and in an extremely stable state even if the width or length of the substrate changes.For example, this substrate transfer device can be used for blasting If the cleaned board is transported to the drying room, both sides of the board will be cleaned and dried evenly and evenly while being transported vertically, improving the quality and reliability of the board. It is extremely effective in increasing

Further, in the substrate transfer device of the present invention, since the substrate is transferred in a vertically erected state, the width of the substrate transfer device can be reduced, and the installation space for the device can be reduced. Furthermore, the structure is extremely simple, the line speed can be easily adjusted, and the handling is extremely easy. It has many advantages such as, and can provide a practically extremely effective substrate transport device.
